Abstract

A mobile communication device is provided. The mobile communication device includes a terminal body, and a speaker module located in the terminal body. The speaker module includes an enclosure located in the terminal body, the enclosure defining a chamber therein, and a speaker having a front surface and a rear surface, the speaker being located in the enclosure such that the front surface of the speaker is exposed from the enclosure and the rear surface thereof is positioned within the chamber, to allow a sound generated from the rear surface to resonate within the chamber. A mutual interference between the sound generated from the front side of the sound emission part and the sound emitted from the rear side thereof can be reduced to thereby improve the performance of the middle and low sound.

Description

technical field [0001] The present invention relates generally to mobile communication devices with improved bass performance, and more particularly, to mobile communication devices with speaker modules. Background technique [0002] A mobile communication device, including a mobile phone or a PDA, is one of many mobile electronic devices that allow a user to send, receive, read or process information wirelessly while on the move. [0003] Due to recent advances in information technology, communication technology, and memory technology, mobile communication devices can directly generate, transmit, or receive multimedia in addition to their original call functions. For example, a mobile communication device can reproduce multimedia files, such as music, movies, or games, and even have a function of receiving Digital Multimedia Broadcasting (DMB) using satellite or terrestrial television channels. For those mobile communication devices equipped with a digital camera, the devi...
